Actually I deliberately didn't say that. I would be happy even with some
people dispensing advise and testing things.

Yes plenty of it is social issues. Some of the perceptions in the other
direction is that Windows users tend to expect everything to work and
not be prepared to help. This may be what they're accustomed to but it
tends to rub open source programmers up the wrong way.

I think if it had been bundled with ghc-6.10 you'd have heard lots more
Windows people complaining.

Note that cabal/hackage does not classify it that way.

Hardly anything releases in sync with ghc and it's unrealistic to think
that it can or should. The special problem for gtk2hs is that it has to
be distributed as a binary so it's guaranteed not to work with new ghc
releases where as most other packages will still build from source.
Again this comes down to lack of developers and lack of access to
Windows hardware. If we had the infrastructure we'd have auto-builders
to make releases with new ghc releases. Perhaps that's something we can
get people to work on. More automation is good. Building all of hackage
on windows and reporting the results would be very useful to everyone.
Not once but continuously.

The more I think about it the more I think that we fortuitously made the
right decision not to bundle cabal-install with ghc-6.10. We didn't
decide to do it due to immaturity but in hindsight that would have been
an excellent reason. As I said before, I hope we'll be able to fix
enough of the things that it'll be ok for the first platform release.

I'm going to obtain a license and set up a VM.
